SEED.,

To all witam it may conce'r'n:

Be it known that I, ERIK L. NYLUND, a citizen of the United States,residing at Crystal Falls, county of Iron, State of Michigan, haveinvented a certain new and useful Improvement in Sleds, and declare thefollowing to be a full, clear, and eXact description of the same, suchas will enable others skilled in the art to which it pertains to makeand use the same reference being had to the 'accompanying drawings,which form a part of this specification.

This invention relates to sleds for use on railroad or railway lines. Innorthern climates where the sleighing lasts a. 'large portion of theWinter it is feasible to have. a sled providedn with ice runnerscalculated to run on rails. Of course the sled can be drawn by anysuitable animal or might be propelled by the aid of an aeroplanepropeller. This, of course is immaterial as the invention resides in thesled itself.

In the drawings,-

Figure 1, is a top plan view of a skeleton of the sled, the platformboards being omitted.

Fig. 2, is a cross-section.

Fig. 3, is an outside elcvation of one of the runners.

Fig. 4, is a detail of one of the runners inverted.

Fig., 5, is a cross-section and enlarged detail showing how the icerunner is'cast upon the sled.

In building a sled of this Character exact details of the constructionare not of moment as these could be varied within considerablelimits'without departing from the gist of the invcntion. Howevcr, I haveshown a convenient skeleton frame for a sled embodying my invention. Itcomprises the two heavy uprights rr., rr which support the runners. Tothese uprights are secured by bolts or otherwise a pair of metal fiangesb, b which drop down below the uprights a and are-located on the insideof the uprights to serve the same purpose as the fianges on car Wheels.The two uprights are joined by metal braces c turnedover at their endsand countersunk into the fianges Z) to which they,

are bolted. Diagonal metal braces d meet to form an X to connect theseross-braces c near their ends. This forms a very strong skeletonstructure. The platform boards e 4 and these may be interlaced with cordas indicatcd in Fig. 4. When this has been done the runner may beinverted into the position shown in Fig. 5 and a wall clamped into theoutside of the upright, which wall can be made up of a Sheet of paper g,a metal strip h, a piece of lath z' or any other suitable way. The clampindicated in this figure may then be clamped over the fiange and thetemporary wall forming a channel. The ends of this channel may beplugged up in any suitable way. It has been thought unnecessary to showthis. Lard has been found to be suitable for doing this. 'Water may.

then be poured into this closed channel and allowed to congeal, therebyforming a runner of ice cast directly onto the side uprights of the sledand held directly thereto by means of the spikes and intertwining cord.As soon as the water is formed into solid ice this' temporary wall maybe -removed The paper will allow the wall to be removed without stickingto the icerunner.

TWhat I claim is:

1. A sled having side uprights provided n'ith depending flanges and`means on the bottom of the uprights for retaining a runner of ice castthereon.

2. A sled having side uprights and spikes drivcn into the bottom of the`uprights for the purpose specified.

3. A sled, having in combination a skeleton frame, including sideuprights, flanges bolted to the insides of the uprights and spikesdriven into the bottom of the uprights for the purpose specified.

4:. A sled, having in combination, a skeleton frame including side'uprights, spikes driven into the bottom of the uprights,` and anintertwined linear member windin throuh the spikes for the urposespecifie 5 5. sled, having in com ination, a, skeleton frame includingside upr-ights, fianges secured to the inside of the uprights, and

fication.
